Sir:
Living in North Dakota, I am always amazed at the number of 300 gallon fuel tanks that are for sale at farm and ranch auctions , usually with the angle iron stands . Hard to disguise but effective on retreats if they can be secured. [Used] underground tanks are a lot tougher to find. [They should be carefully examined before purchase, to be sure that] they don’t rust out and leak fuel into the ground.
